[摘要]：The microcrystalline TINd(MoO4)(2) and TIPr(MoO4)(2) molybdates have been prepared with solid state synthesis on the same synthesis route. The final products have been studied by XRD and SEM. Vibrational properties have been evaluated with Raman spectroscopy. More than 20 narrow Raman lines have been observed in the experimental spectrum of the microcrystals. The most intensive lines related to breathing vibrations of MoO4 tetrahedra have been found at 904 and similar to 930 cm(-1). The earlier proposed empirical relation between Mo-O bond length and stretching mode wavenumber has been tested by the comparative analysis for a suite of sixteen complex molybdates. This well-known relation is found to be unusable for molybdates containing different cations in the crystal lattice. (C) 2011 Elsevier B.V. All rights reserved.
